Even without any vacuum advance at all on the dist. I can't get it to engage the fuel pump. Measurement-wise it seems like it should engage about 1/8", but it just won't engage. I've tried moving the shaft all the way around without being concerned about the timing just to see if it will engage at all, but still no luck. I think I'll try to move the slot in the fuel pump as you suggest and see if this helps.

What is the general consensus as to which way the rotor should point at TDC: toward the fender or toward the #1 spark plug? How does this shape up as far as the orientation of the fuel pump slot and the orientation of the rotor before the distributor goes in the hole is concerned?
